From 5b05e2cbf5b38dfb2410d23adc26703fd37f84f9 Mon Sep 17 00:00:00 2001 From: Konrad Zapalowicz Date: Sun, 9 Nov 2014 02:22:19 +0100 Subject: [PATCH] serial: jsm: Replace magic value with the proper define The changed function flushes the tx UART and the '4' corresponds to the UART_FCR_CLEAR_XMIT value.
